If you go to a class variable usage in the browser, say DefaultDirectory in FileDirectory>>default, and select and right click it, Seaside brings up a walk-back.
I cannot reproduce that. Also note, that this is not Seaside related, but OmniBrowser (I thus reply to the Pharo list).
My fix for this re-writes the existing method a little by using '&' instead of the older 'and:', which I find clearer. What I've done is check that the value can respond to #asNode:
globalReference     | binding |     target hasSelector         ifFalse: [ ^ nil ].     (requestor selectedClass notNil & (binding := requestor selectedClass bindingOf: target selector) notNil & binding value notNil & (binding value class selectors includes: #asNode))         ifTrue: [ ^ binding value asNode ].     (binding := Smalltalk classNamed: target selector) notNil         ifTrue: [ ^ binding value asNode ].     ^ nil
This certainly introduces other bugs. The use of the non-eager #and: is intentional, because if "requestor selectedClass" is nil, "requestor selectedClass bindingOf:" is not supposed to be evaluated. Lukas -- Lukas Renggli www.lukas-renggli.ch
